Migrations create and modify the database tables Dagex needs to function.

Usage

To use migrations in your application you'll need to generate an Ecto.Migration that wraps calls to Dagex.Migrations:

mix ecto.gen.migration add_dagex

Open the generated migration in your editor and call the up and down functions on Dagex.Migrations:

defmodule MyApp.Repo.Migrations.AddDagex do
  use Ecto.Migration

  def up, do: Dagex.Migrations.up()

  def down, do: Dagex.Migrations.down()
end

This will run all of Dagex's versioned migrations for your database. Migrations between versions are idempotent. As new versions are released you may need to run additional migrations.

Now, run the migration to create the table:

mix ecto.migrate
